ECCC GE Review Questions and Answers
100% Solved
What is average daily traffic and design hourly volume for roads? Average Daily Traffic
(ADT): Total number of vehicles x2
Design hourly volume (DHV): .15 x ADT
Hourly volume = ADT/24 hours
Nodal Time Estimate Early Start / Activity # / Early Finish
Duration
Late Start / Resource / Late Finish
How do you determine total float? TF = LS - ES or TF= LF - ES
ex. 7/ 10/ 17
10
12/ / 22
,12-7=5 or 22-17=5
Subgrade Placidity Index (PI) determines what? PI
The cohesiveness/ less of the soil
CBR < 5 is cohesive less (95% compaction)
CBR > 5 is cohesiveness (90% compaction)
What are project compnents? Time, Money, Scope
What are the Gantt chart levels? 1 - Project list
2- Individual project - Master Activities
3 - Individual Project - Construction Activities
What are the components of concrete? 1. Portland cement
, 2. Water
3. Aggragate (gravel/crushed stone)
4. Air
5. Admixtures (Sand)
What method cures concrete?
What is a lump test? Hydration: The method concrete cures
The concrete slump test measures the consistency of fresh concrete before it sets.
What are the 4 conventions to linking tasks? Finish to start (FS) = Task 1 finishes, task 2
starts
Start to start (ss) = Task 2 must start when task 1 starts
Finish to finish (FF) = Task 1 and Task must finish at same time
Start to finish (SF) = Task 2 cannot finish until task 1 starts
